The waste heat generated during biogas production is ideal for drying digestate. The mass reduction not only massively reduces costs, but also concentrates the nutrients contained. A high-quality organic fertilizer is the result.
Our solar-thermal solutions fit perfectly into the agricultural plant concept due to their robust, low-maintenance and automated technology. SolarBatch (Plus) and StorageDryer (Plus) concepts are particularly suitable.

Tailored solar drying concepts
We offer three different solar drying concepts to meet various operational requirements:
- SolarBatch: A batch process ideal for plants with high flexibility requirements.
- SolarFlow: A continuous process suitable for plants with a steady flow of material, with the option of full automation.
- StorageDryer: A semi-continuous process designed for smaller plants
Each concept uses the same basic principle: the use of solar energy to extract moisture from substrates, resulting in a significant reduction in volume and weight.
This not only reduces disposal and transportation costs, but also opens up opportunities for material reuse and recycling.
